TYPE-WHEEL FOR. PRINTING-TELEGRAPH RECEIVERS.

SPECIFICATION forming part of Letters Patent No. 366,628, dated July 12, 1887.

Application iiled March 19, 1886. Serial No. 195,868. (No model.)

To all whom, it may concern:

Be it known that I, CLARENCE L. IIEALY, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Type-lVheels for Printing-Telegraph Receivers, of which the following is a specification.

In the accompanying drawings, forming a part hereof, Figure l is a side view of a figure-Y ro wheel for stocl-quotation printers; Fig. 2, a

view of the surface of the wheel laid out fiat, showing the arrangement consttutingmy invention; Fig. 3, a View li-ke Fig. 2 of a modied arrangement, and Figs. 4L and 5 similar views of arrangements of the characters of tigure-wheels now in use.

In printing-telegraph receivers having two type-Wheels, one of such wheels is provided with letter-types for printing the names of zo stocks, and is known as the letterwheel,7

while the other wheel has figuretypes for giving the price bid or asked for the stocks, and is known as the ligure-wheel. In the preferred form of printer now in use the tape z 5 is printed in two lines, the letter-wheel print- 5o the tape.

ing only on the topline and the figure-wheel only on the bottom line, and hence it becomes essential that each wheel should carry all the characters necessary for printing its linenpon The letter-wheel, with a complete alphabet and the other necessary characters, has thirty types in number, and this number of types is thus made controlling for the figurewheel.

Since there are only ten iigures and seven fractions employed on the figure-wheel, room is left for other characters, such as the letters B and S, which are considered essential and are used, in connection with the figure 3, to denote that a bid or sale is made on three days time,

as 2N-B 3, or 27'iY S 3. Other letters are also used, such as C U R, as well as the marks 23, a9. Periods ordots, usually two or three, are employed, and sometimes thesmall letter QD to divide the price bid from the priceasked, as IIS-@', whiehindicates that llS was bid for the stock and 1183 was asked for it. This division can also be made by printing three periods or dots, as 1185.1'4-.7 5o The fractions have also been repeated for the purpose of filling out the figure-wheel. These features of arrangement will be found in Figs. 4 and 5.

The type-wheels revolve always in one direction, and characters are printed in succession as they occur upon the wheels. If after printing one character it is desired to print a preceding character upon the wheel,it is nec essary to turn the wheel forward another revolution, and this essential feature of operation increases the number of revolutions in adays run greatly. Since the figure line upon the tape has many more characters than the letter line, the loss in timeis more largely in running the figure-wheel.

I have conceived that it is possible to arrange the characters upon the figure -wheel of a two-wheel printer so that the number of revolutions required to print the stock reports for a day will be largely decreased, and it is my object to produce an arrangement which will reduce the number of revolutions to the minimum.

In the drawings, A is the figurewhecl, ol usual or any suitable construction, and arepresents the types cut upon its periphery. It is shown with its characters developed in an arrangement constituting my invention in Figs. 2 and 3.

One feature of my invention, which isindependent of other features, is the arrangement of the figure 3, representing the usual time upon which a time bid or sale is made after all the other characters. The letters B S,whieh precede this figure 3, are preferably placed directly in front of it, as shown in Figs. 2 and 3. This ofitself saves largely in the number of revolutions, since the expression B 3 or S 3 is frequently used, and when used occurs almost without exception at the end of the quotation.

In my improved wheel no capital letters except B and S are used. The letter C, denoting a call, is discarded as not of frequent occurrence. If desirable, the exp ression can be printed by the letter-wheel on the top line ol' the tape, as can also any expressions .for which the letters U R and characters iii, E are used, these letters and characters being all omitted. My improved type-wheel has but IOO one set of fractions, which come next to the three or four characters last on the wheel. I have found that the whole numbers, including the cipher, are most frequently used, andof these the cipher andthe whole numbers below five. My object, therefore, in using one set of y fractions and dispensing with as many other acters. Following the fractions may be the character 61), as shown in Fig. 2, the use of which has been before explained; but this character may be omitted and the partial set of whole numbers made more complete by one number, as shown in Fig. 3, and the expressiou for which the character QD is used be :made by printing three dots or periods.

Not only are the whole numbers greatly predominant in number over fractions in giving the price of the stock, but the number of shares almost invariably leads the price, and this is always printed in whole numbers.

I have found that my improved figure-wheel makes a saving in number of revolutions of from thirty per cent. to fifty per cent.

1. In a figure-type Wheel for stock-quotation printers, `having types for whole numbers and 35 fractionsLthe combination therewith of a figure-type representing the usual time of a time bid or sale located after the other characters, substantially as set forth.

2. In augure-type wheel for stock-quotation 4o printers, having types for whole numbers and fractions, the combination therewith of types Y B, S, and 3, located at the end of the line of. characters, substantially as set forth. f

3. In a figure-type wheel for stock-quotation 45 printers, the combination therewith of types for two sets of whole numbers, one set of fraetions, the, letters B S and the final figure 3, sub

stantially as set forth.

4. Aiigure-type wheel for stoclrquotation 5o printers, having types for whole numbers and fractions, and provided with types fr?, B, S, and 3, located at the end of the line of characters, substantially as set forth.
